I would definitely support a Lisp-centric Git.

Whenever I do Clojure, something that can get difficult when working with multiple people is how the parentheses/brackets/braces stack up, especially when everyone seems to have different opinions on how that works. As a result, if you're not careful, when there's a merge conflict you can have a ton of extra parentheses, which can be irritating to debug.

Obviously this is at some level an issue inherent to Lisps (and to be clear, I love Lisps, and these small headaches are worth it), but I think problems like that could be reduced if our source controls were aware of the ASTs.
